Description
The 849N2505I is a clock synthesizer designed for wireless infrastructure applications. The device generates a selectable 25MHz, 50MHz, 125MHz or 156.25MHz clock signal from a 10MHz input with excellent phase jitter performance. The device uses IDT's fourth generation FemtoClock® NG technology for an optimum of high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection. The device supports a 3.3V voltage supply and is packaged in a small, lead-free (RoHS 6) 32-lead VFQFN package. The extended temperature range supports wireless infrastructure, telecommunication and networking end equipment requirements.
